Hello,

I have a question. I am developing multiplatform app using compose multiplatform, and I am struggling with the AlertDialog and Popups. I needed to set `platformLayers = false` as without it there is no background shadowing. But the Issue I have is that neither AlertDialog nor PopupMenu is accessible via accessibility API on iOS. They are accessible without setting `platformLayers` to `false`.

Is there any option to have both `platformLayers = false` and accessibility API for my dialogs/popups on iOS?

or eventualy I should not set `platformLayers` to `false` and the background shadowing will be fixed in one of the next releases of the compose multiplatform

ah, now I see that I haven’t latest update
<https://www.jetbrains.com/help/kotlin-multiplatform-dev/whats-new-compose-1610.html#accessibility-support-improvements>

so maybe it will be fixed after update to 1.6.10 :crossed_fingers:

Disabling `platformLayers` is a temporary parameter in case of issues, it will be removed in a few versions (not sure when exactly yet). Please make sure that this issue is tracked in our GitHub.

Regarding shadows - it's tricky one. shadows size are not part of layout/measured size and with separate native view we cannot just draw outside. In 1.6.10 I fixed it by measuring real drawings in addition to layout, but... metal drawing + native layout has _some_ sync issues that happen not in our code/Compose, so it can bring some visual jumps during animation. We have some ideas for future improvements here, but it will cost some performance probably :slightly_frowning_face:

lack of a11y without `platformLayers` is known limitation and was one of the reasons of new layers structure introduction

Thanks for the update! I’ll check the new version and the potential glitches. I have some time before publishing iOS app and I believe that everything will be fixed until then :crossed_fingers: 

Hello again :wave:
after switching to the latest version `1.7.0` I see that there is no background shadowing issue, and the `PopupMenu` accessibility works well without setting `platformLayers=false`. But I still have an issue with `AlertDialogs`  as none of the controls inside are accessible by setting `Modifier.testTag` . Is there anything I am missing to be able to have dialogs accessible on iOS side?
